‫Welcome to the tilt sensor interface explain lecture in a structure I'm going to explain when a tilt

2
00:00:12,850 --> 00:00:15,030
‫sensor is and how they work.

3
00:00:16,190 --> 00:00:23,420
‫What is a tilt sensor or tilt sensor is a sensor that tells you if something has tilted or depending

4
00:00:23,420 --> 00:00:30,530
‫upon the type of sensor or if it's at a specific angle and these are most commonly used in game machines

5
00:00:30,710 --> 00:00:38,780
‫toys security systems such as a car alarm so on and so forth any type of item or object that has a sensor

6
00:00:38,780 --> 00:00:44,220
‫that tells you it's been moved most likely has a tilt sensor in it.

7
00:00:44,230 --> 00:00:46,510
‫So how does an actual tilt sensor work.

8
00:00:46,510 --> 00:00:49,760
‫There are various kinds and in different ways.

9
00:00:49,870 --> 00:00:58,000
‫The one that we're working with in our lab is constructed of a metal can that has two metal balls inside

10
00:00:58,000 --> 00:00:58,660
‫of it.

11
00:00:58,660 --> 00:01:05,050
‫And so as you till the the sensor or the actual device the two metal balls will either make contact

12
00:01:05,380 --> 00:01:11,000
‫or lose contact with the two pins which will give you generate a 1 or 0 output.

13
00:01:11,050 --> 00:01:17,800
‫So a tilt sensor has a digital interface which means we can take the output of this tilt sensor and

14
00:01:17,800 --> 00:01:23,870
‫directly connect it to our FPGA and then it's just a matter of reading whether that sensor is a 1 or

15
00:01:23,870 --> 00:01:24,510
‫a zero.

16
00:01:24,670 --> 00:01:29,350
‫And that will tell us either a whether our device has been tilted or not.

17
00:01:29,440 --> 00:01:34,650
‫And so the relatively simple devices but can be very useful to tell you if such as your phone hasn't

18
00:01:34,660 --> 00:01:35,350
‫moved.

19
00:01:35,350 --> 00:01:41,390
‫Is it tilted over or so and so forth you can use these for a lot of different a lot of different applications.

20
00:01:42,520 --> 00:01:44,470
‫Now you understand how tilt sensor works.

21
00:01:44,470 --> 00:01:46,660
‫Let's get started on the tilt sensor a sign that.
